INCINERATOR.

autor nu! Patented Jan. 1926;` 'I y A INQINEITO inclines rearwardlythrough an arch 30 under the grille 30. A door 29 in the front Wallgives access to the ash pit (Fig. A

tunnel or transverse Hue 32 extends from the bottom of the compartment26" through the wall 13 and under the Hooivk 14 in rear of the grates 15and 16. This Hue connects with a smoke stack 33 by means of an angleduct 33. The stack is built in spaced relation to the walls of theincinerator and may be attached to the walls 34 of the incineratorhouse. The stack has a damper 35 above the entrance of the duct 33. Theproducts from the burning chamber pass through the duct 25, chamber 26,grille 30 and chamber 26 to the Hue 32, duct 33 and thence to the stackV33; this produces a down draft between chamber 26 and Hue 32 via chamber26, which has many advantages in an incinerator.

`Within the main burning chamber I mount against the back wall 11upright Hues 36 terminating atthe arched roof 17 and extending throughthe Hoor down into the Hue 32 at the rear side thereof. These Hues 36'have vertical openings 38 in the Hue 32 and wings or baHle walls 37extend transversely of the Hue 32 from said openings. The baHles extendfrom the bottom to the top of the Hue 32 and have Vtheir outer edgesterminating at the central portion of said Hue 32. It will be noted thatthe baille walls are set at an angle and directed toward the entrance tothe Hue 32. By this arrangement a portion of the hot air currents andgases passing through the Hue 32 are deHected into the openings 38,while the main body of the same passes through the Hue to the stack 33.

The hot air currents and gases which are deflected into the Hues 36 aredrawn up into the main burning chamber and recirculated in said chamberand thus increase the heat and promote combustion. The suction createdby the stack 33 will not aHect the upward passage .of currentsthroughthe Hue 36, owing to the baHie walls 37. The duct 25 is amply large toinduce a free escape of the products.

. One of the important features of the in- Vvention is an ash conveyorscrew 39 disposed in a trough40 in front of the ash pit doors 23 and29.` This trough and screw are covered by a plate 41 having openings orgrates 42 therein at the doors. The conveyor screw and trough extend toa suitable discharge point at which an elevator or other disposal meansnot shown) may be located. The conveyor is suitably driven. It is merelyVnecessary to rake the ashes from the pits onto the plate at the fgrates 42, through which the ashes fall into Vthe conveyor Y trough.

' In operating the incinerator a Hre is built `on the right hand (Fig l)grate 15 'in a suitable manner and the garbage and refuse is Cans andother .slow

of the burning chamber, thus being recirculated and intensifying theheat therein.

By means of the damper 34 the draft mayv be controlled. The ashes are'raked from the pits 24 and 31 onto the grates 42 and deposited in thetrough 40 romwhnh they are conveyed by the screw 39.V

Various changes in the size and shape of the different parts, as well asmodifications and alterations may be made within the scope of theappended claims.

`What I claim, is: Y 1

1. In an incinerator, the combination of aY main combustion chamberhaving a plurality of spaced transversely alined grates, an auxiliarycombustion chamber separate from said main combustion chamber anddisposed at one side thereof and parallel therewith, tion chamberdisposed in alinement with the grates in the main combustion chamber, awall between said chambers having a restricted Hue passage connectingthe said chambers for the How of the Hames and products of combustionacross the main coinbustion chamber and laterally `into the auxiliarycombustion chamber, a transversely extending horizontal Hue beneaththeHoor of the main combustion chamber in rear of the 'line of thegrates, a downdraft Hue leading to one end of said passage from theauxiliary combustion chamber in rear of the grate therein, a stack incommunication with the opposite end of said Hue, and vertical returnHues communicating with the horizontal Hue between the downdraft Hue andoutlet to the stack and Vleading from said horizontal Hue to the top ofthe `main combustion chamber. i
